SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
LASER RADIATION AND CONNECTORS
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power
exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10-6 watts.
Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The
maximum radiance from the optical port (under worst case conditions) is 0.8 W cm-2 or 8 x 103 W m2 sr-1.
Do not use optical instruments to view the laser output. The use of optical instruments to view laser output
increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

Ports
C1G124-24
The C1G124-24 (Figure 1-2) has several types of port connections, which include
• twenty-four front panel RJ45 ports (10BASE-T/100BASE-TX/1000BASE-T compliant), and
• four expansion slots for optional Mini-GBIC interface modules.
The 10/100/1000 Mbps fixed front panel ports can operate in either half-duplex or full-duplex
mode, as determined by Auto-Negotiation.
On the C1G124-24, there are four additional slots labeled 21 through 24 for 1-Gbps fiber-optic
connections via optional Mini-GBICs. However, the C1G124-24 can only support 24 slots. Using
any or all of the four additional Mini-GBIC slots (21 through 24) automatically disables the same
number of fixed RJ45 ports on a first-come, first-served basis during the system initialization
process.
For example, connections made to Mini-GBICs in Mini-GBIC slot 21 and 23 before initializing
the system, disables the fixed RJ45 ports 21 and 23. However, if connections are made after
initialization, the Mini-GBIC connections are ignored and the fixed RJ45 ports 21 and 23 remain
enabled.
The 10/100/1000 Mbps fixed front panel ports can operate in either half-duplex or full-duplex
mode, as determined by Auto-Negotiation.
A single LED is provided for each port to indicate link status and activity. The LED is lit when there
is a link, and flashes when there is traffic.

The switch functions can be configured using the WebView™ application, CLI switching
commands, or SNMP.
Each device can be installed as a tabletop unit or installed into a standard 19-inch rack using the
mounting hardware supplied with the rack.
The devices have power supply redundancy capability when connected to an optional external
supply. If the resident power supply fails, the external power supply assumes the entire load of the
device without interruption to network traffic. Each power supply supports its own ac input
connection, which enables each power supply to be connected to a different ac power circuit for
power source redundancy.
1.1.1
Mini-Gigabit Interface Connectors (Mini-GBICs)
The Mini-GBIC installs into a slot to provide 1000BASE-SX or LX network connections. There
are different Mini-GBICs that can provide various types of connectors, such as an MT-RJ
connector, LC connector that supports single-mode fiber-optic cabling, or LC connector that
supports single or multimode fiber-optic cabling. Refer to Table A-2 for a list of supported
Mini-GBICs.
1.2
HALF-DUPLEX/FULL-DUPLEX AUTO-NEGOTIATION
The devices can auto-negotiate the ports’ mode of operation (half-duplex or full-duplex) between
two devices according to IEEE 802.3 standards. During Auto-Negotiation, two devices
automatically exchange information about their current operating mode. The Auto-Negotiation
feature targets the maximum capability that can be reached between the two devices. For example,
the devices can adjust to full-duplex operation when the device on the other end of the connection
can also adjust from half-duplex to full-duplex. If the device on the other end of the connection can
only operate in half-duplex mode, then the devices adjust to operate in half-duplex mode.
Introduction
1-3
Port Trunking
1.3
PORT TRUNKING
Port Trunking is used for load balancing or load sharing. Port Trunking provides a mechanism to
group, or aggregate, multiple links of any technology together to scale the backbone bandwidth
beyond the limitations of a single link. All links are user-configurable so administrators can scale
the backbone bandwidth by adding Port Trunking. The benefits of Port Trunking include the
following:
• All purchased bandwidth is used.
• Distributed, resilient links increase reliability and performance.
• Multiple technologies are supported within a single trunk for maximum flexibility.
1.4
REMOTE MONITORING (RMON)
The devices support the 1, 2, 3, and 4 Ethernet RMON groups. The Statistics, Alarms, Events, and
History groups are enabled on all ports by default.
1.5
PORT REDIRECT FUNCTION
The port redirect function, also referred to as “Port Mirroring,” is a troubleshooting tool used to
map traffic from multiple source ports to a single destination port within the module. This feature
allows frames, including those with errors, to be copied and sent to an analyzer or RMON probe.
The analyzer or RMON probe will see the data as if it were directly connected to the LAN segment
of the source port.
1.6
FLOW CONTROL
Flow control is a method of managing the flow of frames between two devices. It ensures that a
transmitting device does not overwhelm a receiving device with data. This is accomplished by the
transmitting device pausing its transmission while the receiving device processes the frames
already received.
The devices support frame-based 802.3x flow control. Frame-based 802.3x flow control is
supported on all Ethernet ports operating in the full-duplex mode. Flow control can be enabled or
disabled on a port-by-port basis.
Back pressure flow control is not supported on ports operating in the half-duplex mode.
1-4
Introduction
802.1p Port Priority
1.7
802.1p PORT PRIORITY
The 802.1p port priority is used to assign a default priority to the frames received without priority
information in their tag header, map prioritized frames to the appropriate transmit queues, and
prioritize frames according to protocol type. The 802.1p port priority is part of the IEEE 802.1D
standard.
1.8
MANAGEMENT
Management of the module can be either in-band or out-of-band. In-band remote management is
possible through any SNMP-compliant Network Management Software, such as the Enterasys
Networks’ NetSight™ management product. In-band management using Telnet and Enterasys
Networks’ Webview™ is also provided. Out-of-band Local Management is provided through the
RJ45 COM port on the front panel using a VT100 terminal or a VT100 terminal emulator.
Local Management provides the ability to manage the devices. Refer to the Matrix C Series
Configuration Guide for more information.
1.9
SWITCHING OPTIONS
The devices provide 802.1Q switching between all of the front panel interfaces. In the 802.1Q
mode (the default mode of operation), the device functions as an 802.1D switch until you
configure VLANs. Up to 4094 VLANs can be configured. When VLANs are configured, the
backplane ports are automatically configured as Q-trunk ports.
IEEE 802.1Q switching allows migration to Virtual Network technologies without requiring the
replacement of existing equipment.
1.10 STANDARDS COMPATIBILITY
The C1H124-48 and C1G124-24 devices are fully compliant with the IEEE 802.3, 802.3u, 802.3x,
802.1D, and 802.1Q standards. The devices provide IEEE 802.1D Spanning Tree Algorithm
(STA) support to enhance the overall reliability of the network and protect against “loop”
conditions. The devices support a wide variety of industry standard MIBs including RFC 1213
(MIB II), RFC 1757 (RMON), and RFC 1493 (Bridge MIB). A full suite of Enterasys Networks
Enterprise MIBs provide a wide array of statistical information to enhance troubleshooting. For
information on how to extract and compile individual MIBs, contact Enterasys Networks. Refer to
the Release Notes for a complete list of supported MIBs.

UPN Support
1.11 UPN SUPPORT
User Personalized Networks (UPN) is an architecture that allows network administrators to map
network services to identified users, machines, peripherals and other network entities. UPN
consists of three tiers:
• Classification rules make up the first or bottom tier. The rules apply to devices in the UPN
environment, such as switches and routers. The rules are designed to be implemented at or near
the user’s point of entry to the network. The rules are typically at Layer 2, 3, or 4 of the OSI
network model.
• The middle tier is Services, which allows multiple classification rules to be aggregated. Services
can include e-mail and Internet access.
• Roles, or Behavioral Profiles make up the top tier. The roles assign services to various business
functions or departments, such as executive, sales, and engineering.
To implement most roles, UPN requires authentication such as 802.1x using EAP-TLS,
EAP-TTLS, or EAP-PEAP. Authorization information, attached to the authentication response,
determines the application of the UPN policy. One way to communicate the authorization
information is to include the Policy Name in a RADIUS Filter-ID attribute. A UPN administrator
can also define a role to be implemented in the absence of an authentication and authorization.
Refer to the release notes shipped with the module for details.
The rules can only be implemented on the Matrix system by the Enterasys NetSight Policy
Manager, which is described on the web site at www.enterasys.com/netsight.

Connecting Fiber-Optic Cables to MT-RJ Ports
WARNING: Mini-GBICs use Class 1 lasers. Do not use optical instruments to view the
laser output. The use of optical instruments to view laser output increases eye hazard.
When viewing the output optical port, power must be removed from the network adapter.
This section contains the procedures for connecting a 1000BASE-SX multimode fiber-optic
segment from the network or other devices to an MT-RJ port connector of a Mini-GBIC
(MGBIC-MT01) in front panel port 50 or 52.
Each fiber-optic link consists of two fiber-optic strands within the cable:
• Transmit (TX)
• Receive (RX)
The transmit strand from a device port connects to the receive port of a fiber-optic Fast Ethernet
device at the other end of the segment. The receive strand of the applicable MT-RJ port connects to
the transmit port of the fiber-optic Fast Ethernet device.
Enterasys Networks recommends labeling fiber-optic cables to indicate receive and transmit ends.
Many cables are pre-labeled, providing matching labels or tapes at both ends of each strand of
cable.
